I Application filed October 3,-1918. Serial No. 256,665.

To all whom it may concem:

Be it known that I, WILLIAM a citizen of the UnitedStates of America,residing at Hudson Heights, County of Bergen, State of New' Jersey, haveinvented cer'- tain new and use'fullmprovements in Belts,

of which the following is aspecification.

This nvention relates to belts, preferably' to endless bolts.

The invention in its preferred-form' com prises a uplurality of rinwardly disposed threads extending in the direction of length ofthebelt and a plurality of outwardly disposed threads extendingtransversely of such inwardly disposed threads. Theinwardly disposedthreads are preferably of suchl number as to be in close int'irnate,side 'by side, contact when the belt is in more or less taut position;

tact to' one another. i i

Further features and objects of. the invention will be more fullyunderstood from*** the following description and the accom-"f' panyingdrawings, in Which Fig. 1 shows diagrammaticallya perspective View ofabelt' embodying my invention' Fi g. 2 isa detail top plan view of aportion of Fig. .1, certain of the outer threads being removed to showthe inner threads, V

;volutions, each conVolution'h'aving-a length substantially equal to thelength 'ofthe resultant belt.` The nu'mberbfsuch threads 2 is preferablysuch 'that when the belt is in' position,. as'. indicated in Fig. 1, thethreads 2 are in close, side by side, contact with one another; Suchthreads 2 may be formed of convolutions of a number of threads, the ends"of which are either seucured together, end for end, or frictionally orotherwise held 'within the plane or curve passing through such threads2.

Exteriorly of the' threads 2 are a plurality the outwardly 'disposedthreads are preferably in similar close con`-` are-connected or securedtogether, end for end,jor the ends held under or between two outerconv'olutions.

' In the drawngs, such outer strips of threads are shown extendingsubstantially normally to such inner strips or threads 2;

however, the relative angle of disposition of ;the-outer and innerstrips'or threads may be e -varied as desired' i 2 Theresulting woven'beltor other fabric is 'prferably treated with rubber, eaoutchouc,gutta percha'or like non-fibrouscomposition, `Saturated, wholly orpartially, within the' fibr'es of theindvidual-strips or threads 3'. Theextent of inwardfsaturation of the 'treating composition` may bee'arried to the fibres of the threads' Zif desired; exterorly, thetreatment of* the; 'composition m ay be I extended, to; forrn an outer,surrounding coating;asindicated in Fig. 4, whereby the 'entire outer 1faces' of the, belt' "1 are afi'ordedr a. 'substantially continuouscoating of non-fibrous sub'stance. The'inner portion of the inon-fibrons adhesivc' composition 'serves'to bindjthe outer strips orthreads 3 tothe inner strips for threads 2.

Preferably,-the` stitchings 5 of suitable thread are sewed into thestrips or threads 3, and through'the inner layer of threads 2, whichstitchings may be applied prior to the treatment of the belt with theaforesaid non-fibrous composition. Such stitehings are usually disposedin more or less parallel relation and extending longitudinally of thebelt. The stitchings may be comparatively coarse to effect the' generalfunction of tendng to flatten out the coacting layers of threads,comprising the outer transverse threads 3 and the inner longitudinalthreads 2, which function is efected for those types of my. belt whichdo not embody the aforesaid non-fibrous composition.

VVhereas I have described my invention by reference to specific formsthereof, it will be understood that many changes and modifications maybe made without departing from the spirit of the invention, as definedby the appended claims.

I claim.

1. An endless belt comprising a plurality of transversely extendingstrips or threads F GRUPE, v

substantially the length of the belt, the convolutions lying side byside in a common plane, a second continuous thread wound spirally aboutthe first named thread in lateral convolutions lying side by side andnon-fibrous adhesive composition means for binding the threads together.

In testimony Whereof I have signed this specification this 27th day ofSeptember,

WILLIAM F. GRUPE.
